What is the size of 18650 lithium battery cell

The length (height) and diameter of the 18650 lithium battery cell are the same. The current 18650 lithium battery cells on the market are all standard types, with 18 representing the diameter, 65 representing the height, and 0 representing the round cell. The battery capacity of each 18650 battery cell manufacturer is also different. Some only make the battery below 2000mAh, some only make the battery above 2000mAh, some 18650 battery cell manufacturers only make lithium iron phosphate materials, and some only make ternary materials. Cylindrical battery cell size: It consists of 5 digits, the first 2 digits represent the diameter of the battery cell and the last 3 digits represent the height. The unit of diameter is millimeter and the unit of height is 1/10 mm; for example, 18650, 18 means diameter is 18mm, height It is 65mm. Square cell: It consists of 6 digits. The first 2 digits represent the thickness of the cell, the middle two digits represent the width, and the back two digits represent the height. The units are all millimeters; for example, 1665120, 16 means the width is 16mm, and the width is 65mm. The height is 120mm; the concept of 18650 lithium battery size may have two different meanings: one is the size of a bare 18650 lithium battery. Lithium battery manufacturers in this sense are Sanyo, Panasonic, Samsung, LG, and Piccolo. Etc.; the other is the size of the encapsulated 18650 lithium battery. The size in this sense is definitely larger than the size of the bare 18650 lithium battery. Therefore, we must pay attention to the language environment of the concept of 18650 lithium battery size.
